MIRROR MOUNTING,

Application led December 21, 1925. Serial No. 76,747.

This invention "relates to yimprovements in mirror mountings or the like and has particular reference to the provision of framed mirrors suitable forr use as cabinet doors or for hanging upon walls.

In the re-issue Letters Patentto John P. Eustis, No. 131410 August 2, 1910, there is disclosed a mirror mounting wherein amir ror formed from plate glass is heldin a metal frame by means of removable clips. The clips comprise a portion overhanging the back of the glass plate and annif-set portion held by means of flathead counter-sunk screws in the side flanges of the frame. The glass plate is of a smaller area than the frame and suitable spacing blocks are used between the edges of the glass plate and the adjacent edge iianges of the frame to prevent the `glass plate from slipping in the frame. lVhile this structure has met with a large measure of commercial success, it has embodied certain undesirable .features which the present invention overcomes.v

In the prior art structure referredv to the fastening elements havev been visible from the edge of the frame and from an esthetic standpoint this has not been desirable. Also it has been found that in using such a mirror mounting on a cabinet door wherein the mounting is subject to cert-ain shocks incident to opening and closingof the door, the fastening screws have worked loose with the result that at times the holding .clips have become entirely detached from the frame, resulting in possibility of breaking the plate Glass. y b An important object of the. present` in vention to provide a mirror mounting including a metal frame which will be free vfrom visible fastening elements on its outer side or vertical. edges.

Another object ofthe invention is to pro* vide such a device from which the mirror can'be readily removed or replaced without damage to any of the parts of the mountnother object is to provide such a device with increased` mechanical strength coupled with lightness of'weight. p

Another object is to provide such a device which will be simple in construction. neat in appearance, economical in manufacture and an improvement in the art.

lfVith these and other objects in View, the invention residesin the 'novel features of Construction, combination and arrangement @Way of parts hereinafter set forth, illustrated in the accompanying drawings and specifically pointed lout in the appended claims.

' Referring to the drawings wherein similar reference characters vdesignate corresponding parts throughout the several views,

Figure 1 is a perspective view of a wall cabinet, having a door embodying theA invention; 'Y

Figure 2 is a rear elevation of thev improved mirror mounting with parts broken Figure 3 is a transverse sectional view on the line 3-3 of Figure 2;

Figure 4 is a detailed perspective view of one of the stationary hold-down clips used in my mounting; Figure 5 is a sectional view on the line 5 5 of Figure 3 Figure 6 is a sectional view 6 6 of Figure 2; i

Figure 7 is ay fragmentary perspective view of the backing plate `employed in my mounting, and v Figure 8 is asectional view showing parts on the line disassembled and particularly illustrating the method of removing or replacing the glass plate from the frame.` i

The reference character 10 designates a wall cabinet of any preferred construction and equipped with a door11 embodying my invention. The door comprises alframe `12 preferably formed from metal and having front fianges n13, side edge'fianges 14 and top and bottom edge flanges 149, disposed at an angle to each other, in which is securely held a plate glass mirror 15. The mirror 15 is of a smaller areathan the frame 12, such that-va circumferential space 16 separates the edges of t-he mirror from the adjacent iianges 14: and 14a of the frame 12. and

suitable stay blocks .17, which may be of wood or other desirable material, are disposed at spaced intervals within the circumferential space 16. The stay blocks effectively prevent any lateral movement of the mirror in the frame.

Adjacent the vertical edge ianges 14 of the frame 12, I provide a plurality of spaced stationary holdfdown clips designated generally by the reference character .18.r These clips may be formed from metal stampings of suitable resiliency and asbest shown in Figure 4 they embody a longitudinal base portion 19 secu-red as by electric spot-weld- Jing at 2.0 to the front flange 13 of the frame.

A leg portion 2l extends upwardly from the outer edgeof the base 19 and carries at its upper ends a clamping member 22 which overlies the edge of the mirror a suitable distance to hold the same firmly against the flange 13. A protective sheet 28 of cardboard or the like covers the rear side of the glass plate l and may preferably carry ieinforcements 2Liwhich are contacted with a proper amount of pressure by the overhanging clamping member 22. The cardboard backing sheet 23 and its reint'rn'cements 24 are suliieiently compressible to prevent the pressure of the clamping member 22 from damaging the glass plate while at the same time the plate will be very firmly held in place. It is to be noted that the amount of the overhang of the clamping` members 22 beyond the edges of the glass plate is .slightly less than the width of t'he stay blocks i7 for the purpose of facilitating removal of the glassplate as will be hereinaft-ei' described. By using the stationary hold-down clips, spot-welded to the frame, I eliminate visible fastening elements from the front and 'vertical edges of the mounting which makes a neater mounting and reduces to a minimum the possibility of the parts working loose. While I have said that the stationary 'hold-down clips are spot-welded to the flanges 18, they may be permanently secured in some other manner but I prefer the spot-welding because of the limitations of space.

At the upper and lower edges 14a I provide removable clips 25 similar to those disclosed in the previously issued patent and ,comprising as best shown in Figure 6 a threaded wall 2G .for the reception of a fastening screw 27 having its head 28 disposed in a suitable eountersink in the flange lll, and an overhanging portion 29 which overlies the upper or lowei edge of the mirror 15 similarly to the clamping members 22 of the stationary clips.

In order to give a neat finished appcarance to the whole mounting, I provide a backing plate 30 preferably formed of thin sheet tin or aluminum and having 'forwardly extending flanges 31 disposed about its periphery. The flanges 3]. are suitably indented as at 32 in suitable intervals in line with the hold-down clips 18 and 25, said indentations forming detents to engage offset portions in the members 21 and 2G.

The upper extremities of the members 21 and 26 are suliicientlyrspaced from the edge flanges 14 and 14" to permit the passage of the indented portions of the flanges 3l. for frictional engagement therebetween.

In the eventthat it is desired to remove or replace the mirror l5 from the frame, the screws 27 are first ren'loved whereupon the hold-down clips 25 at the upper and lower edges mayA be taken from. the mounting. Thereafter the stay blocks 1T at one of the vertical edges are removed and the glass plate l5 moved overito the position shown in Figure 8 so that its edge ri. will clear the extremities of the stationary clamping members 22, The edge A is then moved outwardly as shown in dotted'lines at B and after it has reachedV a point beyond the plane of the clamping members 22` the plate may be slid in a reverse direction, to remove its other edge C from the adjacent hold-down clips.

From the foregoing it will be evident that I have provided an improved mirror mounting which will be particularly rugged and otlight weight. The outside surface and the vertical edges of the frame will be entirely free from fastening screws or the like yand if necessary the glass plate maybe removed or replaced. Obviouslychanges may be made in the details of construction. and are Y rangement of parts and thev right is heiewithout departing from the spirit of the in# vention.

The invention is not restricted toV framing mirrors, since it may be used just as advantageously in framing pictures, etchings, en gravings, plaques, or other articles which require framing. Therefore, inthe description and claims, where I specifically mention a mirrior and glass plate I imply the equivalents of those terms as well.

Having thus described my invention, what I claim is:

l. In a framed mirror or the like` the combination with a metal frame comprising face and edge flanges arranged substantially at right angles to each other, of a glass plate of less width and length than the frame, removable clips attached to the upper. and lower edge flanges to hold the glass plat-e against the face flange of the frame, additional clips permanently secured to the trarne at its vertical edges and having portions extending over the back of the glass plate a distance slightly less than the normal distance between the edges of the glass plate and the adjacent edge lianges ofthe frame, stay blocks disposed between thel edges of the glass plate and the said edge' flanges, and

a removable backing plate having peripheral' flanges in fiictional clips. j Y

2. In combination ywith a frame and a glass plate, hold-down clips .carried lby the engagement with said frame. said clips having portions extendV ing over .the edges of the glass .plate and having recessed leg portions ad]acent the edges of the glass plate, and a metalbackportions of the clips to hold it in assembled position. A

3. In combination with a frame and a glass plate.y hold-down clips carried by the traine. said clips having clamping portions extending over the edges of the vglass plate and having recessed leg portions; a sheet of cardboard covering the back of the glass plate and held against said back by the clamping portions of the clips, and a metal backing plate overlying the cardboard and the hold-downclips, said backing plate having means for engaging the recessed leg portions of the clips to hold it in assembled position.

4. In a. framed mirror or the like. the combination with a metal frame comprising face and edge flanges arranged substantially at right angles to each other, of a glass plate of less Width and length than the frame, a

protective sheet of slightly compressible material overlying the back ofthe glass plate, removable clips attached to the upper and lower edge flanges to hold the protect-.ive sheet against the glass and the glass against the face anges of the frame, additional clips permanently secured by Welding to the frame adjacent its vertical edges and having portions extending over the protective sheet a distance slightly less than the normal distance bet-Ween the edges of the glass plate and the adjacent edge flanges of the frame, stay blocks disposed between the edges of the glass plate and the said edge flanges, and a removable metallic backing plate overlying the protective sheet and the clips, said backing` plate 4having rictional engaging means for holding it in assembled position.
